Farnestock, USNR), LST Division One Hundred Twenty-Five; credits the Okinawa Gunto operation (assault and occupation, 26 March-18 June 1945) and occupation service in the Far East 20 December 1945-3 March 1946; gives the spec block (2x General Motors 12-567A 900 hp diesels, Falk main reduction gears, three diesel-drive 100 kW 230 V D.C. ship's service generators, 2 propellers 1,700 shp, twin rudders; complement 13 officers/104 enlisted; troops 16/147; displacement 1,625 t light/4,080 t full; 328 ft o.a., 50 ft beam; 11.6 kt trial); lists commanding officers Lt. William J. Loeper (18 Oct 1944-26 Nov 1945), Lt. Oliver L. Upchurch (26 Nov 1945-4 Jan 1946), and Lt.(jg) William J. Fallwell (Jan-Jun 1946); and carries two photographs - the ship with LCT-1267 on her main deck moored alongside LST-768 at Pearl Harbor between 8 December 1944 and 22 January 1945, and the ship beached at Okinawa alongside LST-817.

Coverage ends 30 November 1945; December 1945-March 1946 occupation service and the stateside return are not covered by these file units.

- Class technical data; war-diary yard-event entries cross-referenced
- Finding type
- asbestos_application
- Finding
- Era/design inference for this diesel-powered 1944 LST: no boilers, so the asbestos-relevant applications consistent with the design and era are diesel exhaust lagging and gaskets, engine-room thermal and acoustic insulation, deck coverings and tile, bulkhead and accommodation insulation, auxiliary-piping valve packing and gaskets, and winch/crane brake linings. The documented yard events (Evansville construction, Naval Repair Base Algiers fitting-out, Pendleton Shipyard repair/alteration availability November 1944, and in-service screw repairs at Ulithi and Leyte) are the periods during which installed materials would have been applied or disturbed.

- Finding
- NARA's official guidance states that 'the use of asbestos in U.S. Navy materiel from 1941-1961 is a frequently requested topic' and prescribes the per-hull research pathway: RG 19 (Bureau of Ships) general/confidential/secret correspondence filed by hull designation - for this hull, 'LST811' (1944-built), class 'LST542 Class', type 'LST'; private-yard correspondence under Navy Filing Manual code QM - 'QM/Missouri Valley Bridge & Iron' for the builder; General Information Books (RG 19); and Board of Inspection and Survey material reports including RG 38 Entry P 1-G 'Amphibious Vessel Material Inspection Reports, 1940-1978'. The guide also notes sister ships built at the same yard are the closest machinery analogs - for this hull, other Missouri Valley Bridge & Iron Evansville LSTs.

- Finding type
- gov_survey
- Finding
- GAO's report (fieldwork at Long Beach and Norfolk Naval Shipyards) documents the era's shipboard material environment and policy: 'although all ships contain some asbestos in such components as clutches and electric cables,' thermal insulation was 'the Navy's major use of asbestos aboard ships'; thermal-insulation specifications were changed to asbestos-free only in 1973 and some ships were delivered with asbestos insulation as late as May 1978; the October 1975 removal policy (replace only damaged insulation or that removed for repairs) was modified January 1979 to selective replacement in high-maintenance areas, with 30-50 percent of insulation expected to remain untouched for a ship's life.

- Hull-number collision documented and resolved: ex-USS LST-53 (Dravo, Pittsburgh; redesignated APL-59 September 1954) was transferred to the Republic of Korea in May 1955 and served that government as Chang Su (LST-811). Korean-service references to 'LST-811' describe ex-LST-53, NOT this record's USS LST-811, which was sold for scrapping 4 November 1947 and never served a foreign government.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, material schedule, hazmat disclosure, or docketed case naming LST-811 was found in the public sources searched (see search_ledger). The only 'asbestos' content naming this hull class is law-firm marketing material of the banned-source class (e.g., a mesothelioma listicle for 'LST 542' that wrongly lists a 'boiler room' on a diesel ship). CourtListener could not be queried this session - the authenticated helper reported the daily quota exhausted (~10.2 h to reset) - so docket-level litigation status is open, not negative.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - the 1944 construction era and documented yard/repair periods are consistent with era-standard materials. The hull was scrapped in 1947-48, before asbestos regulation and record-keeping of the modern era, so a scrapping-yard hazmat record is unlikely to exist. CourtListener blockage is an access gap, not a negative result.
